Frequently Asked Questions
How do I know if my exhaust needs repair or a full replacement?
At Lou's Custom Exhaust in Brockton, Massachusetts, we look at how much of the pipe or muffler is affected. A small hole or loose joint is usually repairable, but heavy rust across multiple sections calls for replacement.
Why does my car sound louder than it used to?
A louder exhaust note usually points to a leak, a hole in the muffler, or a disconnected pipe somewhere in the system. The sound gets worse as the damage spreads, so it is worth having it checked early.
What are the warning signs of a failing catalytic converter?
Reduced power, a rotten egg smell, poor fuel economy, and a check engine light are the most common signs. A rattling noise from underneath the car when the engine is cold can also point to internal damage.
What is the difference between shocks and struts?
Shocks control how your suspension absorbs bumps, while struts combine that function with structural support for the vehicle's weight and steering geometry. Which one your car has depends on its suspension design.
Why do my brakes squeal or grind when I stop?
Squealing often comes from a wear indicator warning you that pads are getting thin, while grinding usually means the pads are gone and metal is contacting metal. Either sound means it is time for an inspection.
